Documentation
type ProjectionMap key position serialized = Map key (position, serialized) Source #
A ProjectionMap just stores the latest snapshot for each UUID.
emptyProjectionMap :: ProjectionMap key position serialized Source #
projectionMapTVar :: IO (TVar (ProjectionMap key position serialized)) Source #
tvarProjectionCache :: Ord key => TVar (ProjectionMap key position serialized) -> ProjectionCache key position serialized STM Source #
A ProjectionCache that uses a TVar and runs in STM.
embeddedStateProjectionCache :: forall s (m :: Type -> Type) key position serialized. (MonadState s m, Ord key) => (s -> ProjectionMap key position serialized) -> (s -> ProjectionMap key position serialized -> s) -> ProjectionCache key position serialized m Source #
A ProjectionCache for some MonadState that contains a ProjectionMap.
